OIL-FEEDING DEVICE.

SPECIFICATION forming part of Letters Patent No. 763,301, dated June 21, 1904.

Application filed pr 28, 1903- To all whom it may concern.-

Be it known that we, I/VILLIAM IN. MATHEWs and CARL BAUER, citizens of the United States, and residents of Eureka, in the county of Juab and State of Utah, have invented a new and Improved Oil-Feeding Device, of which the following is a full, clear, and exact description.

This invention relates to a means for introducing a supply of lubricating-oil into steam on its way to the engine; and it consists in certain peculiar devices by which the flow of lubricant may be regulated at will and kept feeding at a steady rate.

This specification is an' exact description of one example of our invention,while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section taken through the steam-pipe and oil-feeding devices. Fig. 2 is a horizontal section looking upward from the line of the section. Fig. 3 is a fragmentary plan view of the plug of the valve in connection with which the oil-feeding device is employed, and Fig. 4 is a perspective view of one of the cut-off plates.

In the drawings, (0 indicates the valve-casing, having the connections a, adapted to be joined to the steam-pipe sections.

6 indicates the valve-plug, which is horizontally disposed and fitted in the casing, said plug having a port 6, constituting the steampassage, and a smaller port 6 passing from the port 7/ outward to the upper side of the plug and constituting the oil or lubricant passage. The plug 7) is also provided in its upper face with a tapering transversely-disposed groove 5, which leads to the port b and the purpose of which will be fully described hereinafter.

The upper portion of the valve-casing a is formed on its inner side with a transverse groove (62., this groove having in its upper wall a counter-groovea" and the two grooves serving to receive the sliding cut-off plates 0. The said plates are two in number and are each provided on their upper faces with racks c, fitting in the counter-groove a and meshed Serial No. 15 L637. (N0 model.)

with pinions (Z, also located in the countergroove (4 and fastened to stems (Z. Said stems are mounted in suitable stuffing-boxes a, formed on the valve-casing a, and are provided at their outer ends with finger-wheels (Z which permit the ready rotation of the stems (Z.

0 indicates the oil-cup, the stem 6 of which is threaded into the upper side of the case a, so as tov communicate with the grooves a and a and so that when the plug 6 is turned fully to open the port 6 the passage in the stem 0 will be in true line with the port 6 In the use of the invention the closure-plates c are adjusted toward and from each other to regulate the size of the orifice through which the oil passes, and by moving the closureplates into tight engagement the oil-cup is entirely out off and no oil will be fed. The groove 7)" allows the oil to pass into and through the port 5 before the plug has been turned fully to the position shown in Fig. 1, and by means of this arrangement the lubricant may be fed into the steam-pipe before the same is fully open to the steam.

Various changes in the form, proportions, and minor details of the invention may be resprted to at will without departing from the spirit and scope thereof. Hence we consider ourselves entitled to all such variations as may lie within the terms of our claims.

Having thus described our invention, We claim as new and desire to secure by Letters Patent 1. In an oil-feeding device, the combination with the valve-casing and the plug therein, the latter having a main port and a transverse connecting oil-feed port therein, of an oil-cup arranged to deliver oil to said transverse oilfeed port, and two closure-plates mounted between the valve plug and casing and movable toward and from each other to command the discharge from the oil-cup, and means for operating said closure-plates.

2. An oil-feeding device, comprising the combination with a valve-casing and the valveplug having a main port and a transverse connecting oil-feed port therein, of an oil-cup arranged to deliver oil to said transverse port, a closureplate commanding the discharge from the oil-cup, a rack on the closureplate, a pinion meshed with the rack, and a stem meshed with the pinion and mounted to turn in tlievalve-casing.

3. The combination of a valve-casing and a plug therein, the latter having a main port and a transverse connecting oil-feed port, of of an oil-cup arranged to deliver oil to said transverse feed-port, a closuredate curved to lie snugly against the side of the valve-plug, the valve-casing having a recess therein recciving the closureplate, and said closureplate being movable to control the outlet from the oil-cup, and means for operating the closure-plate.

4. The combination of a valve-casing and a plug therein, the latter having a main port and a transverse connecting oil-feed port, of an oil-cup arranged to deliver oil to said transverse feed-port, a closure-plate curved to lie snugly against the side of the valve-plug, the valve-casing having a recess therein receiving the closure-plate, and said closure-plate being movable to control the outlet from the oil-cup, and means for operating the closureplate, said means comprising a rack on the closure-plate, a pinion meshed with the rack and a stem attached to the pinion and mounted to turn in the valve-casing.

5. An oil-feeding device, comprising the 3 6. An oil-feeding device, comprising the combination with a valve-casing and a valveplug having a main port and a transverse connecting-port, of an oil-cup arranged to deliver oil to said transverse port. a closure-plate fitting between the plug and casing and curved concentrically to the plug, said plate being movable to control the discharge from the oilcup, and means for so moving the closureplate.

In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
